Mapaipi achitsulo a SSAWAmapangidwa ndi zitsulo zopota ngati zinthu zopangira, zotulutsidwa pa kutentha kokhazikika, ndikuwotcherera ndi njira yodziyikira yokha ya waya ziwiri zopopera m'mbali ziwiri. Ukadaulo watsopano wopanga uwu umatsimikizira kulondola kwambiri komanso kulimba, zomwe zimapangitsa mapaipi athu kukhala abwino kwambiri pakugwiritsa ntchito mizere yamadzi apansi panthaka.

Chitoliro cha Mzere wa Madzi Pansi pa Pansi

Mtima wa izichitoliro chachitsulo chozungulirandi kapangidwe kake kapadera kozungulira. Chitsulo chozunguliracho chimalowetsedwa mu chipangizo cholumikizidwa cha chitoliro ndipo pang'onopang'ono chimakulungidwa ndi ma rollers angapo kuti apange chubu chozungulira chopanda kanthu chokhala ndi mpata wotseguka. Chimatha kusintha kuchuluka kwa cholumikizira chotulutsira, ndipo mpata wolumikizidwa ukhoza kuyendetsedwa pakati pa 1-3mm kuti zitsimikizire kulumikizana kosasunthika komanso kolimba. Kuphatikiza apo, malekezero onse awiri a cholumikizira cholumikizidwacho ndi osalala bwino, zomwe zimapangitsa kuti chikhale chomaliza bwino.

Mapaipi achitsulo a SSAW ali ndi makhalidwe angapo omwe amawasiyanitsa ndi mapaipi achitsulo achikhalidwe. Kapangidwe kake kozungulira kali ndi mphamvu zabwino kwambiri komanso kukana mphamvu zakunja, zomwe zimaonetsetsa kuti njira yoperekera madzi ndi yotetezeka komanso yodalirika. Kuphatikiza apo, njira yolumikizira yapamwamba kwambiri imatsimikizira kuti malo olumikiziranawo sakutuluka madzi ndipo amaletsa madzi kulowa kapena kuipitsidwa. Ndi kapangidwe kake kolimba komanso kulumikizana kotetezeka, chitolirochi chimatsimikizira kugwira ntchito kwanthawi yayitali ndikuchepetsa zosowa zosamalira, zomwe zimapangitsa kuti chikhale yankho lotsika mtengo pa ntchito iliyonse yamadzi apansi panthaka.

a. Njira yochotsera poizoni m'thupi imatchulidwa motere: FF: Chitsulo chophwanyika bwino chokhala ndi zinthu zomangira nayitrogeni mu kuchuluka kokwanira kumangirira nayitrogeni yomwe ilipo (monga osachepera 0,020% ya Al yonse kapena 0,015% ya Al yosungunuka). b. Mtengo wapamwamba kwambiri wa nayitrogeni sugwira ntchito ngati mankhwala akuwonetsa kuchuluka kwa Al komwe kuli 0,020% ndi chiŵerengero chochepa cha Al/N cha 2:1, kapena ngati pali zinthu zina zokwanira zomangira N. Zinthu zomangira N ziyenera kulembedwa mu Chikalata Chowunikira.

Chogulitsa chapadera ichi chapangidwa kuti chikwaniritse zosowa zosiyanasiyana za makampani. Kaya kumanga njira zoyendera madzi ndi zimbudzi za m'matauni kapena kunyamula gasi ndi mafuta achilengedwe mtunda wautali, mapaipi olumikizidwa ndi arc welded ndi chisankho choyamba. Kusinthasintha kwake kumafikira ku machitidwe a mapaipi, kupereka kukhazikika kosayerekezeka komanso mphamvu zonyamula katundu. Chifukwa cha mphamvu zawo zapamwamba komanso kudalirika, mapaipi athu amaposa ziyembekezo zonse pankhani ya magwiridwe antchito ndi moyo wautali.

Ku Cangzhou Spiral Steel Pipe Group Co., Ltd., kudzipereka kwathu kuchita bwino kwambiri sikungasinthe. Ndi zaka zambiri zaukadaulo ndi luso lathu pantchitoyi, timadzitamandira popereka zinthu zabwino zomwe zimakwaniritsa miyezo yapamwamba kwambiri. Malo athu opangira zinthu zamakono komanso njira zowongolera bwino kwambiri zimatsimikizira kuti chitoliro chilichonse chachitsulo cholumikizidwa ndi arc chomwe chimachoka mufakitale chimakhala chapamwamba kwambiri.

Mwachidule, chitoliro chachitsulo chosinthidwa chozungulira cholumikizidwa ndi arc chidzasintha makampani a mapaipi amadzi apansi panthaka. Chitolirochi chili ndi zomangamanga zapamwamba, malo olumikizirana osatulutsa madzi komanso mphamvu zapamwamba, ndipo ndicho chisankho chabwino kwambiri pa ntchito iliyonse yotumizira madzi. Khulupirirani kuti Cangzhou Spiral Steel Pipe Group Co., Ltd. ikhoza kukupatsani yankho labwino kwambiri kuti likwaniritse zosowa zanu. Dziwani tsogolo la mapaipi amadzi apansi panthaka pogwiritsa ntchito chitoliro chachitsulo cha SSAW.
